Hello
I have just purchased my TP-Link Archer VR900
I am just wondering if I should upgrade the Firmware


Firmware version:0.9.1 1.3 v004c.0
Build 151111
Rel.31301n


Hardware version:Archer VR900 v1 00000000
s/n 216565000327

When I visit the website for checking on the firmware upgrade I was unsure of what I should download, so I tried technical help by submitting an e-mail request, it kept saying I failed to submit request even though I completed the 2 pages? So hopefully I can get help here.
Thank you
Gary :)
